I appeared for an interview in Mar 2025, where I was asked the following questions.
- Q1. Difference between objects & maps?
- Ans.

Maps have a size property that returns the number of key-value pairs, while objects require manual count...
- Q2. What is the difference between writing a custom hook as a react component & as a function?

useDeferredValue lets you defer a value update until the browser is idle, preventing blocking UI.
Example: const deferredValue = useDeferredValue(value);
